Q: 10. Let (an) be the sequence defined recursively by, a1 = –1, a2 = 7, for n > 3, an = аn-1 + 2ап-2.…

A: It is required to show that, an=2n+3(-1)n for all n.   Let us check for n=1.   a1=21+3(-1)1 -1=2-3…

Sequence and Series

A sequence is defined as a collection of things. Series is defined to sum the things one by one in the sequence.  It was invented by German mathematician Carl Friedrich Gauss.
